Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies) The work of preparing International Standards is normally carried out through ISO technical com-mittees Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee International organizations, governmental and non-governmental, in liai-son with ISO, also take part in the work ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights ISO shall not be held responsible for identifying any or all such patent rights
International Standard ISO 98 was prepared by Technical Committee ISO/TC 72,Textile machinery and machinery for dry-cleaning and industrial laundering, Subcommittee SC 1,Spinning preparatory, spinning, twisting and winding machinery and accessories
This third edition cancels and replaces the second edition (ISO 98:1977), which has been technically revised
